Gini Index The Gini Index is a measure of how evenly income is distributed within a country, ranging from 0 to 100. An index of 0 suggests income is distributed with perfect equality. The higher the number, the worse the income inequality. The data below represent the Gini Index for a random sample of countries. Note: The United States has a Gini Index of 45 and Sweden has the lowest Gini Index.
With a first class having a lower class limit of 20 and a class width of 5:
(a) Construct a frequency distribution.
(b) Construct a relative frequency distribution.
(c) Construct a frequency histogram of the data.
(d) Construct a relative frequency histogram of the data.
(e) Describe the shape of the distribution.
(f) Repeat parts (a)â€“(e) using a class width of 10.
(g) Does one frequency distribution provide a better summary of the data than the other? Explain.
